Drivalia UK - CARLISLE Arvostelua 

A very frustrating business model. Car booked 23/01 via booking.com.
Acknowledgment received soon after. Online check-in complete about 10-days before collect date (due to DVLA code time limitations). On 12/03 whilst preparing to collect the car for a weekend away starting in two-hours I received a call from the branch advising that they have no car available.
The depot advised that they'd only received a notification that morning and due to issues with trains around Glasgow they had nothing available (whilst booking.com still showed available vehicles for the period).
It seems that you can book early at a good price, but if they get a better offer in the interim, they can cancel at short notice. They refused to cross-hire to complete the contract.
Booking.com are no help. Said they would refund - but with accommodation booked this does not help.
Had to book a train for the bulk of my travel at short notice for almost twice the hire car cost.
If I cancel at short notice, there are various levels of financial penalties - but if the hire car company cancels it's simply "sorry".
Extremely disappointing - very frustrating and wholly unacceptable.
I'll not be using them again.
BTW, friendly local staff appear to have to defend and manage a poor business practice.

We rented a car in Carlisle, it was clean and was fine for our needs. Unfortunately we had a flat tire but there was no spare tire and only a can of puncture foam. We waited 2 hours for the repair truck to arrive. He told us that the tire was worn out and should never have been on the car. The people at Drivalia were at first unwilling to cover my costs as I had not bought the insurance. After showing them the worn out tire, however, they promptly reimbursed the costs.
Lesson 1: don’t leave the shop unless they give you a spare tire.
Lesson 2: Drivalia was quite reasonable to deal with once they understood the issue.
